Abstract

L'invention concerne un procédé de comptabilisation d'articles individuels faisant partie d'une pluralité d'articles sur la base de temps aléatoires se produisant en fonction d'un premier intervalle de temps donné, ainsi qu'un système d'inventaire à intervalles de temps aléatoires fonctionnant conformément audit procédé. Ce procédé comprend une première étape qui consiste à transmettre, sur la base de temps aléatoires, des signaux d'information provenant d'émetteurs individuels, appelés 'étiquettes', ces étiquettes étant tirées d'une pluralité d'étiquettes (5a1-5xx), à au moins un émetteur-récepteur maître et au moins un émetteur-récepteur (4a-4n). Les étiquettes individuelles (5a1-5xx) sont apposés sur chaque article individuel faisant partie d'une pluralité d'articles. Les signaux d'information transmis par chaque étiquette (5a1-5xx) correspondant au moins à l'article respectif auquel l'étiquette (5a1-5xx) est apposée. Les temps aléatoires se produisent en fonction d'un premier intervalle de temps donné. Dans le cas où les signaux d'information sont transmis à l'émetteur-récepteur distant ou aux émetteurs-récepteurs distants, chaque émetteur-récepteur distant (4a-4n) reçoit des signaux d'information provenant d'au moins une des étiquettes (4a-4n), à la suite de quoi il transmet le signal à l'émetteur-récepteur maître (3). Après réception par l'émetteur-récepteur maître (3) d'un signal d'information, une deuxième étape débute, qui consiste à transmettre le signal à un dispositif de confirmation (2) connexe. A l'intérieur de ce dispositif de confirmation (2), après réception d'un signal d'information provenant de l'émetteur-récepteur maître (3), une troisième étape débute, laquelle consiste à confirmer que l'article correspondant au signal d'information est comptabilisé.
